Summary
Snipe-IT has CSV formula injection in Activity Report export
Details
Impact
In Snipe-IT v8.6.1 and lower, Actionlog::logaction() stores the request User-Agent header in user_agent. That value is later included in the Activity Report CSV export by ReportsController::postActivityReport() and written with plain fputcsv().
A low-privileged authenticated user can set a formula-like User-Agent, perform a logged action, and have that value stored in the activity log. If an admin or report viewer later exports the Activity Report and opens it in spreadsheet software, the formula may execute.
Example payload:
User-Agent: =HYPERLINK("https://example.com/","click")
